Application filed December 1'?, 191,5. Serial No. 67,437.

To all 207mm t may concern:

Be it kno-wn that I, FRANK PETER CHES- LEY, a citizen of the UnitedStates of America, and resident of the city of Montreal, Canada, haveinvented certain new and useful improvements in Bed-Spring'- LockingDevices, and do hereby declare the following to be a full, clear, andexact description'of same.

This invention relates to catch devices for preventing side slipping ofspring frames from bed rails and appertains particularly to devices ofthis type adapted to be applied to angle iron spring frames and bedrails.

An object of the invention is to improve the construction andarrangement of the above mentioned catches whereby same are adj ustablycarried, without the use of rivets or other additional fastening means,for application to flat top or reverse side rails.

The objects and advantages will be hereinafter more fully described andparticularly pointed out in the appended claims.

For full comprehension however, of my invention reference should be hadto the accompanying drawings forming a part of this specification, inwhich similar reference characters indicate the same parts and whereinFigure l is a perspective view of a portion of a bed and spring showingthe application of my improved catches.

Fig.v 2 is a transverse section, the bed having Hat top side rails;

Fig. 3 is a similar view illustrating the catches in use with the railsin reverse position; and A Fig. e is a perspective view of one side othe spring frame.

A discrepancy in the widths of beds and the frames of springs thereforehas given rise to the difficulty that the spring frame is liable to slipoff the side rails of the bed and to avoid this I have provided a simplyconstructed catch which, when the spring frame is placed in position,will straddle the bed rail and spring frame and lock the two againstsidewise displacement.

Referring now to the drawings 2 indicates the side rails of a bed and 3the frame of a bed spring both of which are formed preferably of angleiron and carried by either the side rail or spring frame but preferablythe latter as shown, is a catch or hook adapted to slip over the bedrail. The catch consists of a fiat vertically disposed strip 4 looselypassed through a vertical slot 5 formed yin and extending longitudinallyof the horizontaler outwardly extending iange of the spring frame at apoint .adjacent Vthe vertical or downwardly extending flange, the upperAend of the strip extending voutwardly over the horizontal flange .ofthe spring frame and beyond same where it is downturned at G to formahook to take .over the bed rail.

Then the spring is lowered into position the hook 6 takes over the fiattop side rail as shown in Figs. 1 and 2 and straddling the bed rail andspring frame prevents the latter slipping off the former. When, .asshown in Fig. 3 the bed rail is in the reverse position with kthe topedge of the upwardly extending flange disposed higher than the springframe Vthe sliding connection between strip 4l and the spring frameenables the catch to move upto take over ythe relatively higher siderail and prevent side slipping of ythe spring, the adjustmentof .thehook in either easeA being .automatic and its straddling positionmaintained by gravity.

ln order to simplify the construction .and avoid the time takingapplication of .rivets or other fastening devicesto secure the strip tothe spring frame, the lower end ,of the strip is bent rearwardlyunderneath the vertical flange of the frame .and upwardly ,over theinner side thereof to form a hook 7 which with the upper hook 6 securely,attaches the strip to the spring frame, the distance between the insideof the two hooks being sufficient to permit of the required verticalmovement of the strip to take over a reverse rail of a bed and permitthe frame to rest upon the inwardly extending flange of said rail.

The length of the upturned portion forming the hook 7 is preferablygreater than the extent of the vertical sliding movement permitted thestrip or greater than the maximum distance between the edge of thedownwardly extending iiange and the bottom of the vinside of the hook sothat such .hook will always overlap the Vertical flange of the frame andso prevent the swinging of the strip about the frame.

The spring frame may be slotted and the locking catches inserted at anydesired intervals, an advantage incident upon the use of folding bedsprings being the prevention by the hooks of the spreading or twistingof the bed rails at the juncture of the two portions of the foldingspring and the consequent dropping of the spring between the side railsof the bed.

What I claim is as follows:

l. The combination with a bed frame having an inwardly extending flange,a frame for a bed spring having an outwardly extending flange adapted torest upon the inwardly extending flange of the bed frame to support thespring and means for preventing the outwardly extending flange slippingoff the inwardly extending flange and consisting of a strip looselydisposed within a slot formed in one of said frames,

such strip having a hook formed at one end and adapted to take over oneframe and a hook formed at its opposite end adapted to take over theother frame.

2. A frame for a bed spring adapted for use with a bed having a siderail with an inwardly extending flange and an upwardly extending flange,said frame having an outwardly extending flange and a downwardlyextending flange, the outwardly extending flange having a slot thereinand being adapted to rest upon the inwardly extending flange of the bedrail, and a strip loosely located in said slot, such strip having a hookat one end to engage the downwardly extending flange of the frame andbeing hooked at its opposite end to engage the upwardly extending flangeof the bed rail and prevent the spring frame slipping olf the latter.

3. A frame for a bed spring adapted for use with a bed having a siderail with an inwardly extending flange and an upwardly extending flange,said frame having an outwardly extending flange and a downwardlyextending flange, the outwardly extending flange having a slot thereinand being adapted to rest upon the inwardly extending flange of the bedrail, and a strip loosely located in said slot, said strip having a hookat one end to engage the downwardly extending flange of the frame andbeing hooked at its opposite end to engage the upwardly extending flangeof the bed rail, the distance between the hooks being suflicient topermit of the required movement of the strip to take over said upwardlyextending flange when the frame rests upon the inwardly extending flangeof the bed rail.

l. A frame for a bed spring, said frame having angularly disposedflanges, the first of which has a slot therein, a strip loosely locatedwithin the slot and of greater extent than the depth of the secondflange, one end of the strip being hooked to take over a bed rail andthe other end being hooked to take over the second flange, said stripbeing adapted to slide transversely of the frame and within the slot tovary the position of the strip in accordance with different positions ofthe frame relatively to varying bed rails and the length of the lastmentioned hook being greater than the extent of the sliding movement ofthe strip transversely of the frame of the spring to maintain such -lastmentioned hook in overlapping position with respect to said secondflange of the frame.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.

. FRANK PETER CHESLEY.
